What are the Samsung DLP Error Codes?

I have a Samsung HLS5086 WX/XAA
It has been turning itself off.
I just replaced the bulb with a Philips OEM.
I completely blew out all the dust several months ago and checked to see if there was any build up. It was still clean.

Naturally the thing turns off when I am not looking.

The last time it went off I believe the red Standby/Temp LED blinked once and the green lamp light blinked twice.

When I turned it on the lamp light blinked 4 times.
The cooling fan appears to be working properly.
